Letters Patent No. 100,761, dated March 15, 1870.

The Sehedwl..v referred to in these Letters Patent and making part of the same.

To all whom it may concern:

Be it known that I, AUGUST G. HEITMANS, of

4 Brooklyn, in the county of Kings, and State of New York, have invented a new and` improved Floating- Mill Power; and I do hereby declare that the following is a full, clearand exact description thereof,

which will enable others skilled in the art to maltev and use the same, reference being had to the accompanying drawings forming part of this specification, in which- Figure l represents a vertical longitudinal section pivoting the superstructure on which .the working machinery is set up, to a lower gate or iioat, and in suspending the paddle-wheels by which the machinery is moved between the said gate and the superstruoture, so that, by adjusting the distance between the two parts aforesaid, the amount of water acting on the paddle-wheel may be regulated at will, and conformed to the amount of power'required. l The invention consists also in the general combination and arrangement of machinery, as hereinafter more fully described.

A. in the drawing represents a dat-boat, of suitable size and form, sufficiently large to float the entire mill and the machinery connected therewith:

rUpon the boat is erected a frame, B, which is or' may be covered by a roof, to protect and in part sustain the operating mechanism.

C is a transverse shaft, hung in the rear end of the l boat, and carrying two paddle-wheels, I) D, between the projecting sides a a, of the boat,'.the lower parts oi the wheels reaching below the bottom of the boat, as show n.

Upon the shaft C is mounted a bevel gear-wheel, I), which meshes into the teeth of a pinion, c, that is mounted upon an oblique shaft, E.

The shaft E extends forward and upward into the frame-work B. v

The boat A is anchored in the streamer tide-water, the anchor-chain F passing over a windlass, G, which is hung near the bow of the boat.

The current ot' the water will always throw the i paddle-wheels behind the anchor, and will, as it strikes the wheels, revolve the same, imparting thereby rotary motion to the shaft E.

To the sides of the boat, near the stern, are pivoted the upward-projecting flanges or eared d, of theplate H, which extends under the lboat nearly or entirely the-whole length of the same, and under the paddle; wheels, as shown.

Near the front end project upward fromthe sides 'of the plate H toothed bars e c, which mesh into pinions fj, that are mounted upon a shaft, I, hung transversely on the boat.

By revolving this shaft I the pinions willl move the racks, and cause the front endof the plate Hlto swing up or down, as may be desired.

A. pawl, g, catching into a pinion, f, or into a rat- Chet-wheel on I, will lock the plate H in the desired position.

The nearer the front end of the plate H is drawn toward the boat, the less water will he admitted to the paddle-wheels, and the less power will consequently be applied. v

The plate H, with its projecting flanges, serves, therefore, as a gate, to regulate the power of the ma.- chine.

'Lfhe paddles lt, on the wheels D, are pivoted, and are, while the water acts on them, held against ribs i, on the fiangesj of the wheels, to be rigid. VVhle they are being withdrawn from the water, they drop from the ribs and swing down, so as to produce no unnecessary resistance and friction.

vThe shaft E has a pinion, la, at its front end, and meshes into a pinion, l, on a vertical shaft, J, which has its bearings in the boat.

By gear-wheels 1:1, the shaft J propels the working- Y shafts L L, which more the mill-stones M, or other apparatus Ato be operated.

Any suitable number of such shafts L and stones M, or their equivalents, may he employed.

A belt, m, from the driving machinery extends to the anchor-windlass G, and another, n, to the shaft I. By throwing either of these belts intonation, the anchor can be wound up and the gate adjusted by the power of the water current.

Having thus described my invention,

I claim as new and desire to secure -by Letters Patent- 1. The combination of the boat A, which carries the paddle-wheels D and the superstructure B ,-with the flanged gate H, which extends below the paddles, to regulate the amount of water admitted to operate the same, as set forth.

2. The pivoted gate H, carrying the flanges d and the racks c, in' combination with the pnions j on the shaft I, all arranged to operate as set forth.

3. The paddle-shaft C, bevel-gears b c, driving-.shaft J and bevel-gears ZK, with the shaft E, journaled at one end in a collar on said driving-shaft, and at the 'other in the upper part of the boat on frame B, all arranged as set forth.

4. The arrangement of' ribs ion the flanges j of the wheels, to hold the swinging paddles firm against the Y impinging tide.
